Excel Horizontal scroll bar drag not working

Also worked for me! Thanks for the solution.

I had lost sometime trying to fix it before I saw your post.

Eric5100you absolute star for posting this solution. It bloody worked! This was driving me insane. Only on the horizonal bar. It was slightly different bug where the horizontal bar was all jittery and I couldn't hold and drag it, it would skip. I could click on the space after the bar and it would jump find, but not when holding and sliding . 

To confirm I first tried selection all columns that had hidden cells but that didn't work. 

So I CTR+A to select all and unhide and that did the trick! 

Eric5100 I made an account just so I could tell you I love you. Thank you so much for this working solution. More than once have I received a spreadsheet created by someone else that has this issue, and it drives me nuts. Thank you thank you thank you.
